.Letters Patent No. 94,485, dated September 7, 1869.

IMPROVEMENTIN nnmmcawaeoivs.

The Schedule referred to in these Letters-Patent and making part Of thesame:

marked thereon, in which drawings- Figure l is a plan view of myinvention.

Figure 2 is a side elevation of the same on the line x x, fig. 1.

Figure 3 is a broken section of the end of a crossbar of the lower body,showing the method of secur- 7 ing the metallic strap thereon.

Like letters represent like parts in each figure.

The nature of 'my invention is an improvement in' dumping-wagons,particularly for agricultural uses, and consists, mainly,-in an upperbody, which traverses back and forth upon trucks working in channels inthe rails of thelower body, and upon a roller at the rear end of thelower body. This upper body is so constructed that it is held by its ownWeight in position upon the lower body, and maybelifted fromthe samewithout removing screws or other fastenin'gs. The side rails to thelower body may also be readily removed or replaced by the use-of a newand peculiarly-fastened metallic strap, and, when removed, any commonwagon-body'may be placed upon the same A more particular description ofmy invention is as follows, viz:

I make a wooden frame,.of suitable dimensions, consistingof two sidepieces or rails, A, and three crossbars, B. e

To the outer side of these rails, and extending nearly to each end ofthe same, are secured guides C, of sheetmetal, .which extend below thebottoms of said rails, so as to rest against the outsides of the railsof the lower body.

The bottoms and ends of said rails A are covered with sheet-metal, andnear the front under side in each is a circular depression, D.

Under'the-ccntre bar B, and at each end of it, and secured to the innersides of the rails A, are the hooks E, projecting downward below thebottom of the rails A, and with their points to the rear.

To the inner sides of said rails A, and-near the front ends thereof, arescoured the ears F, which incline, at the bottom, toward the front, andextend a little below the bottom of said rails, and slope upward andforward at their own bottoms.

The lowenbody of this device consists of two side piecesor rails G, withtwo cross-bars H, and is designed to sit upon the under frame of awagon. These rails G have their sides covered, for about half of theirlength forward, with-sheet-metal, and a smaller por- 7 tion of theirsides, at the rear end, covered in the same The rails G are fastened tothe cross-bars H by metallic straps I, which are strips of metal, alittle narrower thanthe thickness, sideways, of the rails G,

and are pivoted, at their upper ends, to the ends of the sheet-metaldescribed as covering the sides of said rails G, and upon; thetop of thesame; thence they bend downward, so as to cover the ends of said rails'G, and then toward the centreof said rails, passing under thecross-bars H, and secured to said 'rails 'by nuts K, upon bolts whichpass down through said rails and straps.

The cross-bars H are halved into the ends of the rails G, so that thebottoms of them are on a line with the bottoms of the rails;

A rod, L, with lever M, is pivoted on the top of the front endof therails G. V

This rod has upon it, at the point where it' touches the inner sides ofthe rails G, two tripping-lugs N,

which project above said rod when the lever M isparallel with the railG, andpoints to the rear.

Behind this rod L, and working upon their own shafts, in slots 0, in themetallic side pieces to rails G, and-between said side pieces, are twofriction met allic rollers P.

The metallic shaft Q is pivoted on the extreme rear end of the rails G,at the top of the same, upon open hearings in the metallic side platesto the same, and has rollers solidly secured to the same, revolving inthe space between said metallic side'plates, and rising to the level ofthe top surface of the rails G;

It is intended to use this device with stakes to support a load, orboxed up in the usual way of wagonbodies.

In operating this device, the upper body or frame AB is placed upon thelower body or frame G B, so that thefriction-rollers P will be near thefront of the cavity in which they work, and under and fitting into thedepression 1); the guides 0 will be on the outside of the rails G thehooks E on the inside of said rails; the lever M will point upward; andthe front of the ears'F just rest upon the tripping-lugsN, In this.position, the rails A rest upon the rails G their entire length.

With these frames so adjusted, and upona proper wagon-body, and loaded,if the driver wishes to dump his load, he presses. down the lever M,which raises the front of the fr'ame. A B, and pushes it toward therear, disengaging the rollers P from the depression D, and bringing thesmooth under side of the rails A to rest upon said rollers, which, withthe rollers R, now sustain the whole load, which may be easily pushed-tothe rear.

When the hooks E engage with the shaft Q, the top frame A B will t'ipup, and the load be dumped. The

driver then tip's back the top A B by hand, and rolls any ordinarywagon-body placed upon the cross-bars HQ What I claim as my invention,and desire to secure by Letters Patent, is-

The constructionoilth'e rails G, of wood, for dumping-Wagons, with sidespartially covered with sheetmetal, as described above, for the purposeof aflording channels for friction-rollers, as above set forth.

Also, the arrangement of the friction-rollers P,as constructed, andoperating in channels in the rails G, and in the slots 0, for thepurpose above mentioned. Also, the arrangement of the friction-rollersR, as constructed, upon shaft Q, and operating in channels at thereareutL of the rails G, for the purpose aforesaid.

Also, thearrangement of the hooks E, as constructed, and for the.purpose-before named.

Also, the arrangement of the shaft L, the lever M, and tripping-lugs N,as for the purpose aforesaid.

Also, the arrangement of the metallic straps I, constructed andoperating as above described. Also, the arrangement of the upper railsA, the guides O, and the ears F, asand for the purpose aforesaid.

Also, the combination of the upper frame AB,pro-

vided with the guides O, hooks E, and ears F, with the lower frame G H,provided with the friction-rollers P and R, shaft Q, metallic straps I,shaft L, lever M, and tripping-lugs N, in connection .with suitablerunhing-gear of awagon, and. operating as before mentioned.

In testimony that I claim the foregoing, I have hereunto set my hand,this 13th day of May, 1869. Witnesses: DAVID S. GARDNER.
